Abstract:

Objective To detecting the expression of nicastrin, N1ICD and hes1 proteins in normal liver tissues and liver cancer tissues of C57BL/6 mice. Methods Twelve 6-week-old male C57BL/6 mice were randomly equally divided into the control group and model group. In the model group, the in situ liver cancer model was established with injection of Hepa1-6 cells into the liver, and the control group was treated with injection of the same amount of normal saline. Liver cancer was verified by HE staining. The expression of nicastrin, N1ICD and hes1 proteins in the normal and cancerous liver tissues was detected by IHC and Western blot. Results IHC results showed that nicastrin, N1ICD and hes1 proteins were localized in the hepatic sinusoidal endothelial cells in the normal hepatocytes, but not expressed in the hepatocytes. The model group showed higher expression of nicastrin protein but lower expression of N1ICD and hes1 protein in the cancer cells compared with the control group. Conclusion NCSTN gene may play a carcinogenic role in mouse hepatocellular carcinoma, while notch1 and hes1 may play a carcinostasis role in the carcinoma.
